To obtain the maximum ambient temperature for your controller (55 °C for the cRIO-9030/9032/9034/9035/9037/9039, and 70 °C for the cRIO-9031/9033/9036/9038), you must mount the cRIO-903x in the reference mounting configuration shown in the following figure. Mounting the cRIO-903x in the reference mounting configuration ensures that your system will operate correctly across the full operating temperature range and provide optimal C Series module accuracy. Observe the following guidelines to mount the cRIO-903x in the reference mounting configuration.

Figure 19. cRIO-903x Reference Mounting Configuration


Horizontal mounting orientation.
Mounting substrate options:
  • Mount the cRIO-903x directly to a metallic surface that is at least 1.6 mm (0.062 in.) thick and extends a minimum of 101.6 mm (4 in.) beyond all edges of the controller.
  • Use the NI Panel Mounting Kit to mount the cRIO-903x to a metallic surface that is at least 1.6 mm (0.062 in.) thick and extends a minimum of 101.6 mm (4 in.) beyond all edges of the controller.
Observe the cooling dimensions in Mounting Requirements.
Allow space for cabling clearance according to Mounting Requirements.
Tip Before using any of these mounting methods, record the serial number from the back of the cRIO-903x so that you can identify the cRIO-903x in MAX. You will be unable to read the serial number after you mount the cRIO-903x.
